buffer damage

[89LT1]

On o good note i just got an email back from the manufacturer. They said it looks like the buffer spring is bad. They are going to replace the buffer and spring.

Thanks for all the help guys...

since we are talking about buffers though would an H2 buffer give a noticeable difference?

I have seen this with a friend's AR before; everything looked good, he replaced the buffer with a new one that was correct, and ruined another buffer.

Turned out he was using a .308 AR spring in his .223 rifle. He accidently swapped them in his parts bin. He didn't realize it until he was trying to solve a reliability problem with his LR-308 and was asked on a forum if he was using a .223 spring. He swapped springs back and everything is fine to this day.

crap i just got it in the mail today

funny they sent it to me in a flat rate envelope so they barely cleared $1 for it with ebay fees

man it sure is rattly

Crap............. we may have gotten the same one. The weights are loose inside, its like two round slugs of weight. Where did it ship from?

It worked for 800 rounds, then it just destroyed itself and sent metal shavings onto the bolt carrier group. At first I thought the pin that holds the firing pin came out and scraped my upper, but nope.

Well I ordered buffers from Bravo Company, if you want to try you are welcome to.

The weights are loose inside.

That is how they are supposed to be.
Those weights slide around inside during operation and ensure that the carrier is fully locked.

so i just weighed my buffer its is just under the 3.0 oz so looks like a standard carbine buffer. Once i get the company to fix this issue and it is thoroughly tested I will be upgrading to a H2.

This is completely going off my own logic here but wouldn't the 308 spring be much stiffer? if they were swapped wouldn't it cause short stroking in the 5.56 Ar and it would smack the rear of the tube on the 308? unles they are different lengths?

They have different numbers of coils and different rates and different compressed lengths.
A 5.56 AR spring will not allow full carrier rearward travel in a 308 AR.

cool i didnt think they would be that different. good to know

Crap! My old one was missing a few pieces. It did not have the small discs and only had two weights.

Dang, you are kinda far. I was on your website and looking at a few of your services, are you open for same day service on weekends?
